HOMER P. K. PEOK, OF RYE, ASSIGNOR TO WVILLIAM II. JACKSON 8t (30., OF NEWV YORK, N. Y.

VENTILATING FIRE-PLACE AND OPEN GRATE.

SPECIFICATION forming part of Letters Patent No. 411,393, dated September 1'7, 1889.

To all whom it may concern:

Be it known that I, HOMER P. K. PEGK, a citizen of the United States, residing at Rye, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Ventilating Fire- Places and Open Grates; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure 1 of the drawings represents a front elevation of the fire-place, a portion of the front casing being omitted. Fig. 2 is a transverse section of the same, exhibiting the relative position of the air-heating dues in connection with the ingress and egress passages through which the air passes to be heated and discharged. Fig. 3 represents a perspective view of the connected series of air and smoke passages or fiues. A corresponding series of hoods or trough-shaped deflectors of the smoke and burning gases which arise from the coal-grate and pass through the smoke-fiues are represented in Fig. 6. Fig.4 represents avertical transverse section of the air-flues, smoke-fines, and smoke and gas deflectors in their relative positions. Fig. 5 is a pespective view of the chamber through which the heated air issuing from the airheating fiues passes to enter the apartment to be warmed, in which chamber is located the water-tank and sponge-screen or air-puriand flame deflecting hoods which constitute a separate or detachable element of the fireplace.

Fireplaces for heating air by passing it through chambers and conduits surrounding and above the fire-grate, and thence conducting it into a room or apartment to be warmed thereby,have been long in public use. Among the early inventions of this nature is that described in Charles Neers patent of May 31, 1858, in which ail-is heated by being drawn through a chamber at the back of the coalgrate, thence through pipes arranged transversely above the fire-grate into an air-chamher, also over the grate, and from there it may be conducted to any apartment through pipes.

Furnaces with air-chambers above the firepot have been long in use, into which outdoor air is admitted and thence when heated conducted to rooms to be warmed thereby, and steam-boilers and furnaces each have also been made so as to conduct the burning gases and other products of combustion through tubes which pass through a receptacle for either water or air, and which had provisions or means for introducing water or air and for egress of steam generated or the air thereby heated. Such being the well-known state of the art, my improved fire-place might in a general sense be said to be included within the familiar domain of articles of this class, yet in its peculiar details, purposes, and operations it will be found on examination to differ essentially from all such articles hitherto produced.

A prominent element of my present invention consists in the means I have devised for more completely burning the gas and smoke generated from the fuel, and consequently more effectively heating the air drawn through chambers and fines for warming the rooms of a dwelling house. These means I term a series of hoods or inverted troughs connected to plates which support them at their ends, and arranged over. the open smoke-fines of a fire-place, vertically adjustable, and provided with alternate smoke'flues and air-dues above the coal-grate placed at and within the throat or mouth of the chimney upon the plates of the fireplace. Another important element of my invention consists in means of cleansing and moistening, and, if desired, disinfecting and agreeably odorizing the heated air as it is admitted to apartments of a house, and for these purposes I have devised a peculiar sponge screen, diaphragm, or strainer connected with or communicating at the bottom with a water-tank and arranged to intercept and yet permit the heated air to pass through inter- 5 stices of the dampened sponges and out of the chamber in which such screen and tank are located in front of the air-heating tubes to an apartment, the object being to cleanse, moisten, and tincture, and to impart aromatic roe odors to the dry air which is heated by pass ing in contact with hot plates and fines of the fire-place. The sponge-screen is a kind of diaphragmextending vertically and longitudinally across the hot-air chamber and reaching into the water-tank, which also eX- tends the entire length of the ornamental grating and is located at the bottom thereof, and being composed of pendent wires with sponges upon them that are in contact with each other the fluid in the tank will be carried up by capillary attraction and diffuse,

itself throughout, the entire screen or diaphragm, and the heated air in its passage through the interstices of this wet spongescreen will become moistened and impregnated or tinctured with whatever disinfectant or aromatic substance may have been introduced, dissolved, or commingled with the water of the tank. The combination of the series of hoods with the smoke and air flues is such that each hood is arranged to occupy a position directly above and in suitable proximity to the smoke-flues to cause a reversion of the current of burning gas and smoke and deflect them downward upon the upper surfaces of the air-heating tubes from opposite directions, whereby the combustion of the smoke and gas will be increased while in immediate contact with the air-flues, and consequently a higher degree of heat will be communicated to the air-heating tubes or flues.

In the drawings, D D denote the back plates of the fireplace, between which air entering from without through opening N or elsewhere is heated as it is drawn up behind the grate E and passes through the hot-air flues B. Thence it passes through chamber 7 and the sponge-screen S, and finally through the ornamental grating a into the apartment to be warmed thereby. Of course this fireplace like any open grate will radiate heat from the burning fuel.

D" D denote the side plates of the fireplace, and the chambers between them respectively at each side communicate with the air-chamber B at the back of the fire-place. The left-hand front of the fire-place in Fig. 1 is covered by the facing J. A part of the ornamental grating a in front of chamber 7, in which the tank NV and screen S are located, is omitted, so as to exhibit the outer ends of the air-heating tubes B, which pass directly across the fire-place above the coal-grate E.

H denotes the air-ingress damper, and F the ash-box. The hoods or combustion-deflectors C are not shown in Fig. 1, but are represented in their proper position above the flattened smoke-flues in Fig. 2, also as de tached in Fig. 6.

The series of combined air-flues B and combustion-flues A, together with the wide flanges which form the chamber 7 and the narrow flanges at the edges of the wide flanges, by means of which the combined series of flues is tightly fastened to the upper edges of the side plates and back plates of the fire-place, as shown in Fig. 3, will be cast as one piece.

Above the series of hoods 0, within the chimney B, there is a gas or a smoke combustion chamber M, provided with a damper T, to regulate the draft. The ornamental grating Ct is removable to afford access to the watertank NV and screen S. The wires of this screen, upon which small sponges are secured by thrusting the wires through them, are suspended upon a rod upon which they are hooked, may be adjusted laterally in relation to each other, whereby the screen may be made more or less compact as a sheet of sponge. This capability of adjusting enables the ingress of hot air to be increased or diminished, according to the requirements of heat and ventilation of the apartment into which theheated air will enter.

It may properly be observed that fire-places constructed with these improvements serve most effectively to change the atmosphere of an apartment by the constant introduction of fresh external air, which is warmed to any desired degree, and before it becomes vitiated is expelled and replaced by pure air by the natural draft of the fire-place, the impure or vitiated air being drawn off through the chimney. This perfect ventilation continues un interruptedly so long as combustion of fuel proceeds in the coal-grate and the ingress damper H is open.

It is apparent that this improved fire-place, with its capabilities of ventilating and im* parting to the heated air moisture and aromatic odors and disinfecting rooms in which it is used, will be found especially adapted to chambers, where pure air is so important, and of great advantage in rooms of invalids,'in hospitals, &c.

Having described my invention, I claim and desire to secure by Letters Patent- 1. A fire-place and a fresh-air passage in the rear of said fire-place and in operative contact therewith, in combination with a se- ,ries of alternated smoke and fresh-air flues,

' said fresh-air flues establishing communication between said fresh-air passage and the apartment and said smoke-flues establishing communication between said fire-place and the chimney, and a series of deflecting-hoods above and parallel with said smoke-flues, the spaces between said deflectors being above said air-flues, substantially as set forth.

2. A fire-place, a fresh-air passage in the rear of said fire-place and in operative contact therewith, and a series of alternated smoke and fresh-air flues, said fresh-air flues establishing communication between said fresh-air passage and the apartment and said smokeflues establishing communication between said fire-place and the chimney, in combination with a series of vertically-adj ustable deflecting-hoods above and parallel with said smoke-flues, the spaces between said deflectors being above said air flues, substantially as set forth.

3. A fire-place, a fresh-air passage in the rear thereof and in operative contact there- IIO and in direct communication with the apartment, fines connecting said fresh-air passage and said hot-air chamber, and an open liquidholding reservoir within said hotair chamber, in combination with a screen or diaphragm extending across said hot-air chamber and in operative contact with the liquid in said liquid-reservoir, substantially as set forth, whereby the air heated by said fireplace must pass through said screen before entering the apartment.

4-. A fire-place provided with projecting lips or ledges, a fresh-air passage in the rear of said fire-place and in operative contact therewith, and a series of alternated smoke and fresh-air fines, said fresh-air fines establishing communication between said fresh-air passet forth.
